This paper describes seagrass species and percentage cover point-based field data sets derived from georeferenced photo transects. Annually or biannually over a ten year period (2004-2014) data sets were collected using 30-50 transects, 500-800 m in length distributed across a 142 km(2) shallow, clear water seagrass habitat, the Eastern Banks, Moreton Bay, Australia. Each of the eight data sets...

A fourth production region for the globally important Antarctic bottom water has been attributed to dense shelf water formation in the Cape Darnley Polynya, adjoining Prydz Bay in East Antarctica. Here we show new observations from CTD-instrumented elephant seals in 2011-2013 that provide the first complete assessment of dense shelf water formation in Prydz Bay. After a complex evolution involv...

In this study, we present the relationships between total length, unburied and shell width length net weight for critically endangered Pinna nobilis. This is first transplantation study in which live specimens of P. nobilis have been used estimating length–weight relationship by deploying length. Length–length were all linear cases (r2 > 0.900), whereas was negative allometric with values ex...

Rhododendron is one of the largest shrubs and is well known as a garden plant because of their evergreen leaves and various flower colors. The present study investigated the variation in amino acids in the differently colored flowers of Rhododendron schlippenbachii. Analysis of the Rhododendron flowers revealed 22 types of amino acids. The amino acid content varied greatly depending on the diff...

Nectar robbers are thought rarely to pollinate flowers, especially those with sexual organs hidden within corollas. In this study, we examined whether robbers pollinate flowers of distylous Primula secundiflora. Distylous plants have two floral morphs. Pin flowers have long styles and short stamens, and thrum flowers have short styles and long stamens. Flowers of P. secundiflora were commonly r...

fifteen yarrow populations from different species achillea millefolium l., a. biebersteinii l. and a. nobilis, from different geographical areas of iran were studied using 24 morphological traits and peroxidase profiles. comparison of mean values of different phenotypic traits show a. millefolium and a. biebersteinii l. had higher plant height and crown diameter; however, a. nobilis had higher ...

Flowers, as repeated modules on a plant, may show population dynamics that correspond to ecological models for population growth. We hypothesized that rate of flower production (birth rate), number of open flowers per day (population size) and flower duration (longevity) should be related to plant resource status. With dioecious species, resource demands of male or female function would contrib...

Xylosandrus compactus (Eichhoff) (Col.: Curculionidae, Scolytinae) is an ambrosia beetle species native to subtropical Eastern Asia, with great concern due its high invasive ability. This has invaded 54 countries worldwide, including 4 European (Italy, France, Greece, and Spain); it was detected in Mallorca (Balearic Islands, Spain) October 2019. In the present work, X. recorded for first time ...
